درباره این کتاب:
Recent
decades have seen significant changes in
the biota of the Mediterranean and the
Black Sea due to the introduction of
non-indigenous species. Reliable
scientific data on the dynamics of their
distribution and abundance are essential
to understand their ecological and
economic effects. This review – in
addition to providing images and
descriptions of relevant species to aid in
identification – presents a unique
historical and regional perspective on
these species’ impacts, based on many
years’ worth of research. The Black Sea’s
primary invaders come from the
Mediterranean. Species like the comb jelly
Mnemiopsis leidyi have caused major
declines in biodiversity in the region by
crippling key segments of the food chain.
Similar results have been noted in the
Marmara Sea, a crucial water exchange
point located between the Aegean Sea and
the Black Sea. Infiltration into the
Mediterranean comes from both the east and
west – with Lessepsian species passing
through the Suez Canal and fish and
invertebrate species originating from the
Atlantic expanding their ranges. As of the
publication of this review, over 900
non-indigenous species have been reported
in the Mediterranean and almost 300 in the
Black Sea, with these numbers expected to
rise in the future. Numerous Lessepsian
fishes are commercially relevant and have
been absorbed into local markets,
particularly in the eastern Mediterranean
region. While these species are targeted
through various fishing techniques, many
others are simply discarded due to a lack
of value and there are even some, such as
lionfishes, pufferfishes and several
species of jellyfishes, that present
immediate dangers to human health.
Stewardship of native species, regional
cooperation on the enforcement of legal
measures, increased public awareness and
the creation of marine protected areas are
thus essential to minimize and reduce the
impacts of non-indigenous species both in
the Mediterranean and the Black Sea.
